The Rotator cuff muscles stabilize the shoulder joint, they consist of four muscles supraspinatus, infraspinatus, teres minor and subscapularis.
Since the shoulder joint is the most mobile joint in the body these muscles can be injured in many different ways, such examples include an awkward fall or blow to the shoulder, forcefully throwing a ball, a repetitive action at work like using a mouse on a computer can cause overuse problems.
Symptoms of a Rotator Cuff injury:
dull ache in the shoulder
